BYMZ%QW Patented Oct. 14, 1952 UNITED STATES 2,613,616 HATCH SKIRT AND INSULATION 'PAN SUPPORT Edward S. Cisco, Highland, Ind., assignor to Standard Railway Equipment Manufacturing Company, Chicago, 111., a corporation of Dela- Application April 1, 1950, Serial No. 153,343

This invention. relates to railroad refrigerator cars used to transport perishable commodities and. maintain such commodities while in transit within a predetermined range of temperature. The invention relates generally to an end bunker refrigerator car having a roof formed of a plurality of roof sheets extending from side plate to side plate of the car, and with the end roof sheets, which occur directly over the bunkers, having hatch frames integrally formed therein about the hatch openings through said roof sheets. This type of roof sheet and integral hatch frame is shown and claimed in Patent No. 2,565,706, August 28,1951.

Such type. of integral roof and hatch frame sheet has been found amply strong to support itself in the roof structure without the use of inside carlines or purlins heretofore always thought necessary to support the common hatch frame and hatch cover used in an ordinary roof sheet. Those inside carlines and purlins extending about the hatch frame furnished ideal conditions for attaching means to hold insulation up under the roof and surrounding the hatch frame, but due to limitations in the amount of material which can be pressed in a roof sheet about a hatch opening to form a hatch frame integrally thereabout without tearing, the inner wall of an integrally formed hatch frame, at present at least, cannot extend much more than a few inches below the general level of the roof. With the ordinary carlines and purlins omitted, some means must be provided to support a skirt about the hatch openin and insulation up under the roof and about the hatch skirt, and it is the principal object of the present invention to provide such means.

More specifically the object of the invention is to: provide a rectangular skirt into which the hatch frame extends and lightweight pans about the sides of the skirt, upon which pans the roof insulation is supported.

In an end bunker car, having a bulkhead parallel with and spaced from the end of the car to form an ice bunker therebetween, it is common practice to provide a ridge purlin extending from the center of the bulkhead to the car end to support the bulkhead in position. It is also common to provide a pair of carlines on opposite sides of the hatch frames for support of said frames. It is a further object of my invention to eliminate said carlines and said ridg purlin and provide purlins only extending from said bulkhead to the car end on opposite sides of said hatch skirts to support said skirts and also provide a much more stable'support for said bulkhead, and at the same time provide ideal conditions for support of insulation about the hatch skirts and in the roof structure.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanyin drawing,

5 Claims. (Cl. 105-377) 2 wherein like reference characters indicate like parts:

Figure l'is a section transversely of the car through one hatch and the upper part of the adjacent side wall of a railway refrigerator car and showing the bulkhead header in side elevation.

Figure 2 is a horizontal section throughthe hatch skirt and showing the insulation supporting pan arrangement on all sides of said skirt.

Figure 3 is a section on line 3-4, Fig. l.

Figured is a section on line 44, Fig. 1.

Since the invention relates to the structure .of end bunker railway refrigerator cars, at and around the hatchwa'ys, only one-half of an end roof sheet and ceiling structure, which includes a hatch, and the upper part of the car wall will be described, the other half of the roof, etc., being identical.

The end roof sheet, or in other words, the roof sheet adjacent the end of the car, is indicated at i, one end of which rests upon the usual side plate I 2 and is provided with a turned-downflange 3 at the end. Between the ridge 4 and eave of the sheet is integrally formed therein an upwardly pressed rectangular embossment comprising upwardly converging side walls 5, downwardlyconverging inside walls (5, with the upper edges of said walls 5 and B being connected by a downwardly inclined shoulder 1 which isof slight inclination so as to form a seat for the gasket of a hatch cover for closing thehatch opening 8.

One side of this roof sheet i is provided with a downturned flange 9 which overlaps and rests upon the upper end of the steel end Ill of the car and the other side of said sheet is provided with an upturned flange l 1 adapted to abut against a similarly formed flange [2 of the adjacent roof sheet and be overlapped by the seam cap I3, as is common.

The car side walls comprise outside sheathing it, the upper margin of which underlaps side plate 2, the spaced side posts it, insulation 11 and inside wood side plate [8 secured indirectly to side posts [6. The end walls are of similar construction, with the exception of vertical posts which are eliminated, the end ill extending between and being secured to the corner posts of the car.

In end bunker refrigerator cars, a bulkhead 20 extends transversely of the car from side to side thereof and spaced from and parallel with end wall ID and adjacent inner Wall of hatch 8. This bulkhead isprovided with a header comprising.

2 members each having a portion 2 l-2l disposed vertically and in abutting relation with overlapping flanges 22-22 extending laterally in the same direction from upper end of portions 2 4-2 I, and with flanges 2323 extending laterally in opposite directions in the same planes so as to rest upon the top of bulkhead 2!]. Flanges 23-23 terminate in reflanges 2424 which abut andoverlap the outer surfaces of the upper end of bulkhead and are secured thereto in any desired manner.

At the inner side of the hatch 8 and extending from upper flanges 2222 of bulkhead header to the steel end I0 is a 2 bar, the web 26 of which is disposed horizontally with the inner end thereof resting upon and being secured to flanges 2222 of bulkhead header. At the eaves end of the hatch 8 is a similarly disposed angle member with one flange 2! thereof disposed horizontally and with the inner end resting upon and secured to the flanges 2222 of the bulkhead header. The 2 bar is provided with a vertically disposed flange 25and the angle member is likewise provided with a vertically disposed flange 28. A rectangular hatch skirt 29 is provided surrounding and underlappin the inner walls 6 of the hatch frame so'that said inner walls 6 extend downwardly within the upper margins of the hatch skirt 29. The lower margins of opposite walls of said hatch skirt abut and extend flush with upstanding flange 25 of the Z bar and flange 28 of the angle member and are secured thereto respectively by bolts 30 and 3 I. The 2 bar is also provided with a downturned flange 32, which is coped out at its ends to permit inner end of web 26 to rest upon-and be secured to flanges 22-22 of the bulkhead header. The other end of the Z bar, adjacent the car end I 0, has the end portion of said web 26 flanged upwardly, as at 33, which abuts a surface of a wooden breaker block 34 and which block 34 in turn abuts the web of an outwardly facing channel 35, the edges of the flanges of which are welded to the inner surface of end sheet In. Flange 33, block 34 and channel 35 are all secured together by a single bolt 36 passing therethrough. The same structure is employed for securing the corresponding end of angle 27 to end sheet [0 and accordingly the same reference characters are applied thereto.

As previously set forth, there is a hatchway 8 on either sideof the ridge of the car, with a hatch skirt 29 supported by an angle 2'! and a 2 bar 26 extending from bulkhead header to the steel end sheet ID as just described. A ridge pan 40 extends between the Z bar flanges 32, the opposite sides of said ridge pan being provided with downturned flanges 4| which abut flanges 32 and are secured thereto by spaced bolts 42. The opposite ends of said ridge pan 4a are likewise provided with downturned flanges 43 which are of sufficient depth to reach and be secured to reflanges 24 of the bulkhead header and the inner end plate 44.

Extending between the eaves side of hatch skirt 29 and the inner side plate 3 is an eaves pan 45 having a downturned side flange 46 secured to inner side plate It and a similar side flange 4! which is secured to the sides of the hatch skirt 29. The ends of the pan 45 are also provided with downturned flanges 48 and 49 secured to the abutting flanges of the side pans 50 and hereinafter described.

Adjacent the side of hatch skirt 29 facing the end of the car is an end pan 5!] having a shallow side flange 5| abutting and secured to adjacent side of hatch sheet 29. The opposite side of pan 50 is also provided with a deeper side flange 52 which is secured to the inner end plate 44. Flange 52 extends beyond the end of the pan, is cut away to pass under 2 member 26 and laps flange 43 of ridge pan 4!] and is also secured to inner end plate 44. At the eaves, pan 50 extends under angle 21 and the end is provided with a the space between hatch skirt 29 and bulkhead header 23. This pan 55 has a downturned side flange 56, secured to skirt 29, an end flange 51, secured to inner side plate l8, a side flange 58 which is relatively wide so as to extend downwardly and be secured to the bulkhead header. Flange 58 extends beyond the inner end of pan 5!] and is cut away so as to extend under Z bar 26 and flatwise against flange 43.

From the above, it will be apparent that the pans form an insulation supporting means to hold the insulation up under the roof and about the hatch skirt; the purlins not only act as bulkhead header reinforcements but also support the hatch skirt. The ordinary carlines are eliminated so that there is some reduction in weight of'the material used.

I claim:

1. In a railway car having a roof sheet, a hatch opening through said roof sheet, a hatch skirt depending from the margins of said hatch opening, purlins at opposite sides of said skirt for supporting said skirt, and pans extending laterally from the lower margins of said hatch skirt and said purlins for supporting insulating material about said skirt between said pans and said roof sheet.
